Abstract (en)
According to the invention is described an electric motor comprising a rotor, a stator (1) having a plurality of stator teeth (4) having a rectangular cross section, concentrated windings comprising stator winding coils (6) wound on the periphery of the stator teeth, and a stator slot (8) formed between two adjacent stator teeth. The motor further comprises winding coils (6) comprising a winding of a conductor having a rectangular cross section, whereby an unoccupied space (10) is created in the stator slot (8) between the windings (6) of adjacent teeth (4), and comprises a cooling arrangement (12; 14; 16; 18, 20) in the unoccupied space (10) of the stator slot (8).
